What exactly are adjustable dumbbells?
Adjustable dumbbells are devices intended for free weight training or, in other words, weight training. Typically, a dumbbell is made up of two equal weights attached to an axle, with disks of equal weight at each end. In the case of adjustable discs, you can select the discs according to the weight with which you want to train.
What materials are adjustable dumbbells made of?
Not all adjustable dumbbells are made from the same materials. They usually change depending on the audience they are intended for. Depending on your experience and your level of training, you will choose one or the other. Although cast iron is the most common material, there are different options on the market:
- Cast iron: They are the most traditional and are generally aimed at professionals. Usually, gloves are required to train with them, but the best models have the grip covered with other materials – like neoprene – to make it easier to grip.
- Plastic: This is the most economical material and these dumbbells are intended for beginners. In these cases, the filling material is usually sand.
- Chromium: They are very similar to iron dumbbells and are usually lined with synthetic rubber to make them easier to grip.
Types of dumbbells and weights
The weights to be fixed on the bar can be with disc weights, hexagonal or with a more flattened side, thus allowing good stability when the dumbbell is placed on the ground.
There are also automatically adjustable dumbbells. Certainly, this represents a certain cost, but these dumbbells have a resolutely futuristic design and their very innovative technologies will make your workouts even more enjoyable. Indeed, thanks to this type of dumbbells, weight adjustment is done automatically.
They are placed on a base and thanks to a selector, you just have to choose the load you want to have on the bar.

In addition, they are easier to handle than a weight bar. Thanks to adjustable dumbbells, you can progress quickly and safely, without needing to be constantly followed by a professional. A minimum of mastery to position yourself well, and off you go for an effective workout! The best thing to do before you start using adjustable dumbbells is to assess the maximum load for you. It is better to start with lighter weights and increase them over the sessions, rather than forcing too much from the start at the risk of injuring or discouraging you.
Here is an overview of the different exercises you can do with a pair of adjustable dumbbells:
- On the arms, you can use the biceps and triceps thanks to the “curl” movements or vertical extensions.
- For the shoulders, there are several possibilities between the lateral or frontal elevations or even the military bench.
- The bench press or the incline bench press is very effective exercises for working the pectoral muscles.
- You can also work your thighs with lunges or squats, or even solicit your calves by placing the tips of the feet on a wedge or a stair step, holding a dumbbell on each side.
- For the back, the movements are a little more limited, because it is necessary to make pulling movements to make the back muscles work well.
There are a wide variety of movements that you can exercise with simple dumbbells, and by gradually increasing the weights, the results will be felt for a very short time and you will gain strength and power quickly.

But the grip must not only be comfortable, but it also has to be with support and strong enough to support the weight of the plates. You should know that styles with the cheapest prices tend to be the most likely to bend and break in the short term.
Spectrum of weight
This is very important to know in advance before adding an adjustable dumbbell type to your routine because it refers to the different weights that it can reach. Most of these have a maximum of between 22 to 45 kg. The important thing is that you do not acquire a model that has a lower weight spectrum than what you need.
Adjustment margin

Maybe, if you are starting in the training with dumbbells or if you are a person who is going through a process of rehabilitation of muscles or old age, you need to start with very low weight and to increase the weight in a very subtle way.
In this case, what is required are adjustable dumbbells with a very low weight gain, so a set that allows fractions of increases or decreases in weight through a wide range of adjustment can be very useful.
Ease of adjustment
Having a very complicated team to use and adjust can make your training very frustrating. Imagine having to unscrew a lock or make any other system unfriendly to you, it can be a serious problem during your routine. Above all, because it can hinder it and because it can disrupt your time in case you have a tight schedule.
So it is best to have an adjustable weight system that automatically increases or decreases the weight levels with a system as simple as through a dial or a switch. And a good brand is able to offer this benefit.

While cost perhaps should not be your biggest factor in the choice, it is desirable to get adjustable dumbbell models that are not of excellent quality, but also have an affordable price.
